To all whom it may concern Be it known that l. \YiLLAm) liivixo' TWOMBLY, a citizen of the 'lfnited States, residing in the borough of Manhattan, in the city, county, and State of New York, have ini ented new and useful Improve ments in Motor-"chides. of which the following a specifi a tion.

This invention relates to motor vehicles, and it is the object of the invention to provide an improved manner of controlling the driving means. comprising a driving eleme'nt, such as a motor and a fly wheel fixed to the motor shaft mounted in the chassis frame to have to-an(l-fro movement. whereby to throw the fly wheel into and out of operative relation with a power-transinitting element to couple and unconple the motor with the driving; wheels of the vehicle, the powentransinitting element being adjustable whereby to change the direction and speed of the driving wheels.

A further object of the invention is to so; mount the motor in the chassis frame that it may be readily and quickly removed for the purpose of making repairs or the substitution of another motor. and as read ily placed in position in the flillliOa 'ith these objects in view I construct the frame of the chassis so that the motor or engine may be readily and quickly rolled in from the front of the frame and have a limited to-and-fro movement therein. the fly wheU of the motor Sfil' lllfj as a friction drive wheel and also as one member of a clutch to couple the meter with the driving wheels. The means to effect relative changes of speed and direction between the motor and drive wheels consists of a driven wheel *rnounted on and adjustable along a shaft with its axis transverse to the axis of the motor. the periphery of which wheel is adapted to frictionally engage with the face of the fly wheel: the said wheel also serves as the other member of the clutch to couple the motor to the drive wheels. Suitable means are provided to adjust said wheel ilone its shaft and lock it in its adjusted positions. fr m an id driven wh'eel Fluff to the drivin.

In the drawings [have shown my-im- .9 5 proved driving mechanism as carried by tlzo chassis frame of a motor vehicle of osutalf; construction. comprising e bars 1. .of'

bent inwardly at the forward end, at 4, so that the frame atthis end will be of less width than the rear and permit of a short turning radius. said frame being supported upon the wheel axles 5 by springs '(l, and

A readily and quick removable driving element. in the present instance consisting of an internal combustion engine, (designated in a general way by M,) the frame of whzef-i has laterally projecting hanger 116 arms 8 at the front and rear with rollers 9 thereon to engage in the channel portion of the sidebars 1, 2, whereby the motor is mounted in the frame, is adapted to he rolled into and out of the same, and to have a limited to and fro rolling movement therein. The side bars 1, 2 may be provided with a piece of angle. iron 10 upon which the rollers run, and-which also serves to strengthen the said bars.

To maintain the motor firmly in position in the frame and yet permit a free and easy to-and-fro movement therein. it is pro ided with alining pins 11 projecting from the rear of the motor frame toengage in openings in lugs 12 fixed to the chassis frame, and alining pins 11 projecting from the front of the motor frame to engage in open.- ings in a releasable. bar or plate 13 extend ing across the fron,t of the chassis frame, the said plate being releasably secured by means of bolts 14 passing through lugs 15 fixed to the frame members 1, 2 and also passing through the projecting ends of the plate, nuts 16 in the form of a cap having a screw threaded engagement with said bolts to draw and lock the plate in position, the said nuts being carried by offset brackets 17 fixed to the front plate, the nuts being .of such length as to always project through said brackets. and provided with a flange 18 to permit of a limited movement between the bracket 17 and the plate 13 to prevent the loss or misplacing of said nuts when the plate is removed. The said nuts are also provided with oppositely flattened portions for the application of a wrench or the like.

A friction drive wheel 21 is fixed to the power shaft 22 of the motor, the said wheel serving as the fly wheel of the motor and also to couple the latter with the driving wheels of the vehicle. The face of the wheel 21 is adapted to frictionally engage with the periphery of a drivenwheel 23 mounted on a. shaft 24, journaled in brackets 20 fixed to the side bars 1, 2, (Fig. 9,) with its axis transverse to the axis of the motor, the said wheel rotatable therewith and adjustable along the same to ellect relative changes of speed and direction between the motor and. drive wheels of the vehicle. The periphery of the said wheel 23 may be provided with a suitable friction material, in the present instance in the form of a band 25 of fiber or the like. To permit of the sliding or adjusting of the wheel 23 along the shaft 24 and rotate therewith, the shaft has a key or spline 19 (Figs. 8 and 9) to engage in a keyway in the said wheel. Power is trans mitted to the drive wheels of the vehicle from the shaft 24 by means of a chain 26 passing around a sprocket wheel 27 on the shaft 24 and a sprocket wheel 28 on a countershai't 29, and chains 30 passing around sprocket wheels 31 on the ends of the shaft 25) and sprockets 32 on the hubs of the driving wheels of the vehicle. Radius or reach rods 34 are connected to the countershaft 29 and the rear axle 5 whereby to maintain the axle in proper alincinent and to take up any slack in the chains 30.

The mechanism to adjust'the wheel 23 along the shaft 2i (Figs. 8 and 9) consists of a pair of rack Iii) mounted to have sliding movement in a bracket 37 fixed to the side bar 2 and through which the shaft 24 also passes, and at one end pivotally connected to pins projecting from a collar 88 engaging in an annular groove or" recess in the hub of the wheel "'23. The bracket 20 liXcd to the sidc member 2 also has openings to permit of the passage of the free ends of the racks 311. Also rotatably carried by an arm 37' integral with said bracket is a vertical shaft Zl9to which are fixed pinions 40 to mesh with the racks 3G. The shaft 39 is rotated by means of a chain 42 passing around a spro ket wheel 13 fixed on said shaft and a sprocket wheel all fixed to a hollow shaft 45') snrroiimling and ii'otatively mounted on a steering post 46, which post is connected in any suitable manner to the steering mechanism on the front wheels of the vehicle. ()n its upper end said shaft 45 is provided with a hand lever l7 and a spring latch iii to engage with either one of a' series of teeth or notches in a circular rack 19 fixer] to a tubular post 50 surrounding the hollow shaft 45 and secured to the body 7. (,Fig.

The motor normally maintained toward the front of the chassis framewith the fly wheel 21 out of engagement with the wheel 22 by means of a spring or springs s, (Fig. 2,) in the present instance shown as leaf springs fixed to the motor frame and projecting laterally therefrom to abut against the lugs 12, the springs being provided with a perforation or forked portion for the pasof the pins 11. To impart a. rearward movement to the motor {to couple it with the driving wheels of the vehicle, ,by throwing the wheel 21 into frictional engagement with the periphery of the wheel 23 and lock it in such position, I provide a lever 51 fixed to a rock shaft 52 journaled in lugs projecting from the plate 13., ,the said leverprojecting through a slot in the foot-board of the vehicle body 7 and has pivotally secured thereto a foot pedal 53. Also fixed to said shaft 52 area pair of arms 54 to engage with rollers 55 carried by brackets secured to.the motor frame. The motor is locked in its rear position with the wheel 21 in engagement with the wheel 23 by a pawl 5 engaging witha rack 57 secured to the foot-board, the said pawl having a link connection .58 with the foot pedal 53.

F or the present purposes have deemed it necessary to show only so much of the mo I substitution of for and of the chassis frame as will sutlice for a clear understanding of the invention,

and it will be obvious that in a construction of this character suitable automatic or quick releasable or flexible couplings are provided in the control mechanism, the connection with the source of fuel supply, and the mufflers, as well as with a water cocler when the motor is of the water cooled type.

The operation of my improved driving mechanism is substantially as follows: As-

suming the parts to be in the positions indicated in Figs. of the motor or friction wheel 21 in frictional engagement with the wheel 23 to coir ple the motor with the driving wheels of the vehicle, the said wheel 23 being in a plane coaxial with the axis of the motor and no power transmitted through said wheel to the driving wheels of the vehicle. Should it be desired to propel the vehicle forward, the

pawl 56 is thrown out of engagement with the rack 57 by slightly rocking the foot pedal 53 on the lever arm 51 when the tension of the spring S will force the motor toward the front of the vehicle frame, and the wheel 21. out of frictional engagement with the wheel 23. The latch48 is then thrown out of engagement with the rack 49 and the hand lever 47 moved to the left rotating the hollow shaft 45 in the direction of the movement of the hand-lever 47 and imparting a similar rotary motion to the pinion 35) and shaft 40 through the chain i2 causing the racks. 36 and the connected wheel to move to the left of the axis of the motor, as shown in dotted lines in -Fig. 2. After the wheel :23 has been adjusted to the desired position, which may be indicated on a dial formed integral with the rack 49, the la ch 48 is again permitted to engage with the said rack 49 to lock the wheel in such position. Pressure is now applied to the foot pedal on the lever 51 when a rearward movement will be imparted to the motor and the wheel 21 thrown into engagement with the wheel 23, again coupling the motor with the driving wheels of the vehicle. Should it be desired to propel the vehicle backward, the above operations are repeated with the exception that the handle 47 is mm c-d to the right reversing the direction and rotation of the hollow shaft 45 and thereby causing the wheel 23 to be adjusted to the right of the axis of the motor. By engagement of the pins 11 in the openings in the lugs 12, and of the pins 11 in the openings in the plate 13, the motor is held firmly down on the tracks and yet permitted to have a free and easy to-and-fro movement.

Should it be desired to remove the motor for the purpose of making repairs or the another motor, it is only necessary to unscrew the nuts 16 and pull the plate 13'away from the bolts 16' and the 1 and 2, with the fly wheel front of the chassis frame and with it the rocker shaft 52 and affixed lever 51 and rocker arms 5i, and by raising the plate slightly thefoot pedal 53 will readily .pasS through a slot 7 in the foot board ,of the vehicle body, when the motor may be rolled out from the front of the frame.
